Solution for (2+z)(4z+3)=0 equation:


Simplifying
(2 + z)(4z + 3) = 0

Reorder the terms:
(2 + z)(3 + 4z) = 0

Multiply (2 + z) * (3 + 4z)
(2(3 + 4z) + z(3 + 4z)) = 0
((3 * 2 + 4z * 2) + z(3 + 4z)) = 0
((6 + 8z) + z(3 + 4z)) = 0
(6 + 8z + (3 * z + 4z * z)) = 0
(6 + 8z + (3z + 4z2)) = 0

Combine like terms: 8z + 3z = 11z
(6 + 11z + 4z2) = 0
